... Magnesium-aluminium spinel (MgAl O ) has been considered as a primary condensate in the outflows of oxygen-rich AGB stars and as a potential carrier of the 13 m emission band observed in the spectra of these stars [ 11 ]. Therefore, in the Jena laboratory, a systematic study of the infrared properties of Mg-Al oxides of both synthetic and natural origin was performed in order to derive the optical constants of these materials. ...
